The Supreme Court on Friday asked Delhi government to either amend the master plan to retain millennium bus depot on the banks of River Yamuna or shift it to some other place.The apex court bench headed by Chief Justice T.S.Thakur gave the Delhi government a year's time to act either way.The court made it clear that Delhi government would not get any further time beyond one year to decide the fate of the contentious depot which was set-up in 2010 Commonwealth Games for a period of two weeks to park the low floor buses.Environmentalist have been asking for the shifting of the Millennium Depot contending that Yamuna bank on which it is located is in fact a part of the flood plains of the river.
